Abstract
A data transmitting and receiving device includes: a clock signal generator which modulates a reference clock signal having a reference frequency to produce a clock signal whose frequency changes in a set cycle within a set frequency band; and a frequency range storage which stores a first frequency range as a part of the set frequency band and/or a second frequency range as the rest part of the set frequency band. The first transmitter does not transmit first communication data to a first receiver based on the clock signal having the frequency belonging to the first frequency range and transmits the first communication data to the first receiver based on the clock signal having the frequency belonging to the second frequency range. The first receiver receives the first communication data from the first transmitter based on the clock signal having the frequency belonging to the second frequency range.
